sql选择日期范围明年问题

Question

我正在尝试创建一个select语句，使用以下代码将天数添加到CURDATE：

      SELECT
                po.factory,
                po_item.po,
                po_item.style,
                po_item.style_name,
                po_item.customer_style,
                po_item.colors,
                po_item.material,
                po_item.pairs,
                po.sef,
                po.client,
                ROUND(((po_item.pairs)/12)) as total_ctn,
                style.shoe_dimension,
                factory.official_name,
            DATE_FORMAT(CURDATE()+10, '%m/%d/%y') as FROMTHIS,
            DATE_FORMAT(CURDATE()+17, '%m/%d/%y') as TOTHIS,
            CASE WHEN 
                po.rlsd is not null THEN po.rlsd ELSE po.lsd END AS date
            FROM 
                po_item
                inner join po on 
                    po_item.po = po.po
                inner join factory on 
                    po.factory = factory.id
                      inner join style on po_item.style = style.style
                      inner join client on po.client = client.id
                      inner join divisions on client.division = divisions.id
            WHERE
                divisions.group_division_id = '19'
                AND po.ref is null 
                AND po.status != 'C'
            ORDER BY 
                po.cls DESC

这是如何回报：

    DATE_FORMAT(CURDATE()+10, '%m/%d/%y') as FROMTHIS,
    DATE_FORMAT(CURDATE()+17, '%m/%d/%y') as TOTHIS,

都返回{null}，因为这是明年的日期，因为CURDATE（今天）是2017/12/10 +12应该是2018/01/01但是返回{null}

有谁知道如何解决它？谢谢

然后我想在where语句中使用两者，例如：

      SELECT
                po.factory,
                po_item.po,
                po_item.style,
                po_item.style_name,
                po_item.customer_style,
                po_item.colors,
                po_item.material,
                po_item.pairs,
                po.sef,
                po.client,
                ROUND(((po_item.pairs)/12)) as total_ctn,
                style.shoe_dimension,
                factory.official_name,
                DATE_FORMAT(po.cls, '%m/%d/%y') AS date_cls,
                DATE_FORMAT(CURDATE(), '%m/%d/%y') as date_today,
                DATE_FORMAT(CURDATE()+10, '%m/%d/%y') as audit,
            DATE_FORMAT(DATE_ADD(CURDATE(),INTERVAL 12 DAY), '%m/%d/%y') AS FROMTHIS,
            DATE_FORMAT(DATE_ADD(CURDATE(),INTERVAL 17 DAY), '%m/%d/%y') AS TOTHIS,
            CASE WHEN 
                po.rlsd is not null THEN po.rlsd ELSE po.lsd END AS date
            FROM 
                po_item
                inner join po on 
                    po_item.po = po.po
                inner join factory on 
                    po.factory = factory.id
                      inner join style on po_item.style = style.style
                      inner join client on po.client = client.id
                      inner join divisions on client.division = divisions.id
            WHERE
                po.cls BETWEEN `FROMTHIS` AND `TOTHIS`
                AND divisions.group_division_id = '19'
                AND po.ref is null 
                AND po.status != 'C'
            ORDER BY 
                po.po,
                po.cls DESC

但是没有用

请尝试以下查询：

SELECT DATE_FORMAT(DATE_ADD(CURDATE(),INTERVAL 10 DAY), '%m/%d/%y') AS FROMTHIS
SELECT DATE_FORMAT(DATE_ADD(CURDATE(),INTERVAL 17 DAY), '%m/%d/%y') AS TOTHIS
